I know we require a minimal understanding of the problem and be clear on what is being asked, then I forget how much is minimal. On one end the understanding of the problem is well enough that there is no need to ask on the other so poorly that the question is misguided. If to formulate a good question a person has good understanding of the problem, you would expect good questions to be hard to answer as that understanding is not enough. If answering is wrong, I guess that's it for me.
